print("str1: ", str1)
print("str2: ", str2)
print("str3: ", str3)
print("str4: ", str4)
print()

print("capitalize(str1): ", capitalize(str1))

str3 = "HELLO WORLD!"
str4 = "includehelp.com is a tutorials site"

# printing
print("str1: ", str1)
print("str2: ", str2)
print("str3: ", str3)
print("str4: ", str4)
print()

print("capitalize(str1): ", capitalize(str1))
print("capitalize(str2): ", capitalize(str2))
print("capitalize(str3): ", capitalize(str3))
print("capitalize(str4): ", capitalize(str4))
